“I will not sign off on a roofing project without a written warranty that covers both materials AND labor for at least 10 years. Many contractors provide the manufacturer's material warranty (25 years) but no labor warranty. If the installation is defective — flashing improperly seated, valley not sealed — you're paying for that repair out of pocket. Get labor warranty in writing.”
Schedule your roofing project for spring or fall, not summer or winter. Summer heat causes fresh asphalt shingles to be pliable and susceptible to scuffing from foot traffic; winter rain creates safety issues and moisture exposure for the exposed deck during tear-off. April–June and September–November are the optimal installation months in the Valley.

Permit requirements depend on the specific scope of work. Most structural, electrical, plumbing, and mechanical work in Los Angeles requires LADBS permits regardless of project size. Your contractor should verify permit requirements for your specific project and pull all required permits before work begins.

Yes. Roof replacements are noisy but you can remain in your home. NP Line Design protects landscaping, covers outdoor furniture, and performs magnetic nail sweeps daily to ensure safety.
Rain delays roofing because materials cannot be installed on wet surfaces. LA's dry climate means rain delays are rare (primarily December-March). Most roofing projects proceed without weather delays.
Asphalt shingles are fastest to install (1-2 days for a standard home). Flat roofing (TPO/EPDM) is also fast at 2-3 days. Tile is slowest at 3-5 days due to weight and individual piece placement.
